GT6 rear light swap to TR3 (L549) type

[Ben Hutchings]

I’m swapping to TR3 / MGA etc rear lights. I know a few have already done this. It needs some sort of mod, and I’m wondering how others have done it. Here’s a comparison (note body fitting holes): 

 

The original is at the top, and you can see the fixings for the ‘new’ one are closer together and neither line-up with existing holes. Seems to my three options are:

1) Drill new holes in the body 😮

2) Drill new holes in the lamp bases, somehow keeping the strength previously provided by some pressed profiles around the holes.

3) make up some brackets with studs providing necessary offsets.

I’m favouring option 3 although it’s gonna take the longest. Any ideas? What did you do?

Ben, I went for option 1, painted the holes or you could apply some grease.

I’m going for option 2. Modifying the lamp bases. So far it means 3 new holes in each, and quite a bit of filing on two to allow for screw head clearance and also a new side-entry wire ‘port’. Also one of the bulb holders was rusted beyond repair so I’ve swiped one from one of the old bases and copper-riveted it back in.

It’s been a long while since I did mine but I think I used option 1. Which ever one protect the bare metal.

I used “good quality” led bulbs and I’m told that the rear of the car is more visible in mist or after dark.

Just had a search for LED GLB380 bulbs. Goodness $$$ - But a worthy upgrade I'm sure. The originals are so dim especially without the added reflector thats appears in the later units I'm replacing.

I used the company that Hogie suggested. Good quality bulbs.

Any pics available for a GT6 with TR3 rear lights? Wondered how they look on the car.

[Ben Hutchings]

Not fitted mine yet @Dion, need to grab some seals next time I put an order in, or pass Moss. 

There are a few others in the club that have done it though. Anyone else?

Seem to recall @Greta did this mod recently..? Might have been on the old forum, or I might be completely mistaken
